Economical auto recloser


RCW(N) type economical auto recloser is a class simple combination switchgear which is Solid insulated with vacuum interrupting technology, with silicone rubber coating and simple relay protection and equipped with a spring mechanism ahieve auto closing function under operating sequence O-0.5-CO-15S-CO.


This type aut recloser is basic version auto recloser, which is equipped with 3 current transformer and spring mechanism and economic controller.


RCW(N) type auto recloser is exact terminal switchgear for using at position front of distribution transformer(or secondary substation power transformer purpose of protection breaker)some similar like sectionalizer or breaker with relay protection.


Thus,RCW(N) type auto recloser is Actualy a normal motroized type spring mechanism vacuum circuit breaker with manual and motorized opening/closing device. Its suitable for using on simple purpose grid as a switching and key point protectio breaker.



RCW(N) type auto recloser is very compact design switchgear, which is widely using on worldwide, the voltage rating range from 6kV up to 40.5kV.Insulation level at BIL 200kV max. The current rating range from 630A, up to 1250kA, 25kA.
